A questionnaire about facial skin problems was answered by 3745 office employees with the aim of discovering whether VDU work causes skin disease. From this group, 809 randomly selected persons were examined and interviewed by a dermatologist. There was a relatively good correspondence (87%) between the results from the interviews and the questionnaires, but the questionnaire results corresponded to current status in only 46% of the cases. No important difference was seen between those who were informed and those who were not informed about the purpose of the investigation. There was a relatively wide variation in the correlation between two responses to the same questions. In conclusion, the self-administered questionnaire seems to give reasonably adequate answers regarding the occurrence of more clear-cut symptoms over a period of time, rather than answers regarding the presence of signs at a particular point in time. However, less marked changes might not be picked up particularly well and the use of questionnaires alone cannot be recommended when studying mild skin problems due to a particular exposure in a population.
3745名办公室职员回答了一份关于面部皮肤问题的问卷，目的是探究视屏显示终端（VDU）工作是否会引发皮肤疾病。从该群体中随机抽取了809人，由一名皮肤科医生进行检查和访谈。访谈结果与问卷结果之间存在相对较好的一致性（87%），但问卷结果仅在46%的案例中与当前状况相符。在知晓调查目的和不知晓调查目的的人之间未发现显著差异。对相同问题的两种回答之间的相关性存在较大差异。总之，自行填写的问卷似乎能就一段时间内较为明显的症状出现情况给出合理充分的答案，而非关于特定时间点体征存在情况的答案。然而，不太明显的变化可能无法被很好地发现，在研究人群中因特定暴露导致的轻度皮肤问题时，不建议仅使用问卷。
